SPECIFICATION forming part of Letters Patent No. ceases, dated November 13, 1888. Application filed February '7, 1888. Serial No. 263,307. (No model.) Patented in England 1Iay12,1887, No. 0,981.

To aZZ whom it may concern.-

Be it known that we, WILLIAM SPENOE, of Pemba Cottage, Adelaide Road, Surbiton, in the county ofSu rrey, England, gentleman, and

5 ABRAHAM PULLAN, of 306 New Cross Road, in the county of Surrey, England, engineer, both subjects of the Queen of Great Britain, have invented new and useful Improvements in Applying an Automatic YVord,Figure, and the Like Counter and Register to Type-Writing and Caligraph Machines, (for which I, WIL- LIAM SPENOE, have applied for a patent for a part of this invention in Great Britain, such application being numbered 6,981 and dated the 12th day of May, 1887,) of which the following is a specification.

XVe do hereby declare the nature of our invention to be to provide and attach an automatic counter of words and characters as they are written or printed and the keeping of aregister thereof on machines known as the Remington type-writer, the caligraph, or other similar type-writing machines, so combined with the spacing mechanism of the 2 5 same that the said counter and register may be operated thereby either when it is attached to the machine or detached therefrom; to provide a means of compensating for the unequal throw of the horizontal key-levers of the machine caused by the varying distance between the fulcrum thereof and'the keyboard keys, so as to transmit an equal movement to the counter and register from all the said levers alike; to prevent the actuation of the counter and register by the spacing mechanism of the machine more than once for each word while obtaining any required space between the words; to enable any words or characters desired to be omitted from the count,

0 and to enable the indicating hands or pointers of the said counter and register to be returned to zero without unnecessary movement of the counting and actuating mechanism.

'We attain the objects of our invention in the manner shown in the accompanyingdrawings,wherein an automatic word counter and register and the mechanism for operating the same is shown applied to a Remington type- Writer, to a caligraph type-writer, and upon a base-plate detached from the machine, and in which Figure 1 represents a side elevation of a portion of a caligraph type-writer, showing our said invention applied thereto. Fig. 2 is a part plan view of the same. Fig. 8 shows a plan view of our invention, as applied in the foregoing figures, detached from the existing structure. Fig. 4.- shows the locking-collar for the strikinglevers. Fig. 5 shows the adjust-- ment of the levers on the rocking spindle and the greatest throw of the said rocking spindle and levers. Figs. 6 and 7 show the modification of the striking-lever device shown in Fig.

Figs. 13 and 14: show the con struction of the ratchet-wheel, the lever, the crank, and the back-stop. Fig. 15 shows the connection of the leading screw-bearing with 5 the machine-frame. Fig. 16 shows the connection of the dial with the bearing. Figs.17,

18, and 19 show means for securing the striking-levers to the rocking spindle. Figs. 20 and 21 show the construct-ion of the half-nut, 8o guide, and pointer. Fig. 22 is a side view of our invention on an independent base or foundation plate shown in relation to the framework of a caligraph typewriter. Fig. 23 is a plan view of same without the machine. Fig. 24 is a plan view of an ordinary indexcounter with multiplying-gear as adapted for the purposes of our invention; and Fig. 25 is a view of the units-dial thereof.

In the drawings sufficient only of the typewriters is shown to illustrate the application of our invention thereto, and similar figures or letters represent similar or corresponding parts throughout.

A is the frame-work of the machines, under- 5 neath which there is applied the horizontal key-levers 1, connected with the key-board keys 2, and manipulating the typelevers by the attachment D. Under or over these horizontal key-levers 1, and carried independently of the counter itself in the bearings 4, fixed to the machine-frame A, preferably in the position shown, we place a long rocking spindle, 3, carrying two levers, 7, one at each end, outside the machine-frame A, when our invention is applied to a caligraph or similar typewriter, and inside the said machine-frame A when it is applied to a Remington or similar typewriter, having their top faces at their ends 11 made to fit underneath the spacing-keys 14c or space-bar levers 45, but not connected thereto, and secured on the rocking spindle 3 by the set-screws 18 in such a position that when struck by the spacing key or lever the counter is operated upon. The rocking spindle 3 also carries a series of striking levers or arms, 7 3, inside the machine-frame A, corresponding in number and position to the horizontal keylevers 1, and of various lengths to compensate for the unequal throw of the same, and thus convey an equal and uniform movement to the counter through the rocking spindle 3 from them all. For thispurpose the striking-levers 73 are so arranged that the horizontal key-levers with the shortest throw act upon the longest striking-levers, and those with the longest throw act upon the shortest striking-levers. They are attached to the rocking spindle 3 by a key or feather, 85, Figs. 3, 10, and 18, let into the same and projecting into a keyway in the bosses of the levers, as shown in Fig. 18. Lateral movement of the striking-levers 73 is prevented by the collars 86. In the caligraph these collars have keyways 89, which enable them to pass over the end of the feather and drop into a notch made therein to receive them, a slight turn bringing the solid part of the collar into the notch, thus locking the levers together, as shown in Figs. 3 and 4.. By means of the set-screws 88 they are then firmly secured on the rocking spindle 3. In the Remington type-writer the said feather 85 is only long enough to carry the bosses of the striking-levers 7 3, which are locked by thclevers 7, and the collars 86, secured by pins 87,

as shown in Fig. 10. Instead of these striking-levers 73 being fixed by the above device, they may be separately secured to the rocking spindle 3 by means of a set-screw or pin, 90, which would enable any of the characters in a piece of work to be omitted from the count by loosening the striking-lever 73, corresponding to the horizontal lever 1, representing such character, and turning it down out of reach of the same. A modification of these striking-levers 73 may be made by using two striking-levers only, (numbered 5, Figs. 5, 6, and 7, and 22 and 23,) which may be fixed on the rocking spindle 3 by the setscrews 18 in any convenient position. A striking-bar, 6, is attached thereto by the set-screws 26, and is made with kerfs or notches 74 in its upper surface of various depths to suit the varying throw of the horizontal key-levers. It may also be adjusted on the levers 5 by means of the screws 26 and slots 91, so as to produce the same result as and be a perfect substitute for the striking-levers 73.

The striking-bar 6 may be plain without kerfs, as shown in Figs. 22 and 23, and adjusted on the levers 5, in combination with the other adjustable parts of the mechanism, for the purpose above described; but these modifications will not permit the omission of any characters from the count.

The end of one of the levers 7, when our invention is applied to a caligraph or similar type-writer, carries a slotted link, 8, which may be adjusted to suit the increase or decrease of travel of the various parts between the counter 10 and the spacing-keys 14 and key-board keys 2 by moving it, as may be required, to either of the holes 13 in the under side of the lever end 11. Any suitable counting and registering device may be employed in combination with this actuating mechanism, and in Figs. 1, 2, 3, 22, and 23 we have shown an ordinary-geared multiplying-counter, (which is shown in detail by Figs. 8 and 24,) and is adapted to it as follows: Aratchetwheel, 76, is fixed upon the units dial spindle 75, and is moved by a pawl or ratchet lever, 77, attached to a disk, 78, and engaging the teeth on the periphery of the said wheel 76. The disk 78 revolves loosely on the spindle 75, and carries a pin, 79, which is adjustable in the diameter of the said disk 78 by means of the holes 80, into either of which it may be screwed. The said pin 79 works in the slotted link 8, carried by the lever end 11, the vertical movement of which thus rotates the disk 78, which, by means of the pawl 77, advances the ratchet-wheel 76 the distance or space of one tooth and rotates the spindle 75, thus operating the series of wheels and pinions and 96, the first pinion, 95, of which is carried on the said spindle 75, and so registering the movement of the mechanism.

The operation of the actuating mechanism is as follows: The action from the striking of any one of the key-board keys 2 in writing the first letter of a word or a character depresses the relative strikinglever 73 or the strikingbar 6 and lovers 5, thus rotating the rocking spindle 3 and raising the levers 7, the smooth faces on the ends 11 of which are now against the under side of the spacing-keys 14 or of the spacing-bar levers 4.5. At the completion of a word the spacing key or bar 14 is struck, depressing the lever end 11, with the slotted link 8, thus operating the counter, as already described. The spacing key or bar 14 may now be struck any number of times for any extra space required without moving the counting mechanism, as the levers 7 remain down, the striking-bar 6 or the levers 73 being again up to the under side of the horizontal key-levers 1, ready for the repetition of the operation with the commencement of the next word.

At the end of the piece of work being written the movable hands 16, 17, 18, and 19 on the dials 15 may be returned to zero by simply IIO turning them on their spindles, thus avoiding waste of time and unnecessary wear of the mechanism or breakage thereof by continuing its action through the whole series of numbers, which would otherwise have to be done. The hands 16, 17, 18, and 19 are constructed for this purpose, as hereinafter described, and shown in Figs. 11, 16, and 24.

The counting and registering device which weprefer to use in combination with our actuating mechanism, as described, and which constitutes our gearless automatic word counter and register, is shown applied to a Remington type-writer in Figs. 9, 10, and 11, and is as follows: A lever, 7, is fixed on the end of the rocking spindle 3 outside the machineframe A by a set-screw, 18, and has a slot, 27, Fig. 12, in its end for the adjustment of the connnecting rod orlink 8" by means of the pin 28 in its lower end. The upper end of the link 8" is attached to a lug, 81, on the end of the crank 23 bya pin, 82, or other suitable device. The crank 23 is fitted upon the projecting end 34c of a leading-screw, 31, which is carried by bearings 35, fixed to the frame A of the machine by the studs and nuts 36. The other end of the said leading-screw 34 has a collar, 93, and pin 94 outside the bearing 35 to prevent lateral movement. A ratchet wheel, 33, having upon its periphery fifty teeth (or any number to agree with the pitch of the leading-screw and the marking of the scale) is fixed upon the projecting end 3 1 of the leading-screw 34 in front of the crank 23, and is worked by a pawl or ratchet lever, 31, carried upon the crank-pin 9 and kept in gear with the said ratchet-wheel 33 by the spring 83, which is fixed to the lug 81 by the screw 84.. The leadingscrew 34c extends the whole distance between the bearings 35, to the front of which a registering-scale, 38, is fixed by the screws 32. A halfnut, 37, travels upon the leading-screw 34 and is provided with a split pin, 92, passing through its lower extremities below the leading-screw to prevent its being displaced while in use. In the front part of the half-nut 37 a slot, 39, is cut and its outer face beyond the slot is shaped to form a pointer, 40. Thus, when it fits down over the scale 38 it forms a stay for the same and for the leadingscrew 31, while the scale forms a guide for the half-nut, the pointer 40 on its front indicating the divisions thereon.

The dial 1.5 (which is shown spaced into fifty divisions, but may be spaced into any number to suit the pitch of the leadingscrew and the marking of the scale) is formed with a flanged projection, 68, at its lower side, (shown in Fig. 16,) by which it is attached to the lower part of the bearing 35 by the screw 42, and is fitted over the projecting end 31 of the leading-screw 31, which passes through it, and is then tapered or otherwise shaped at its extremity 69 to receive the dial-pointer 16, which fits thereon sufficiently tightly to travel with the leading-screw 34,, but not too tightly to be turned back tozero, when required,without continuing the action of the mechanism, as hereinbefore referred to, and is kept inits place by the nut 70. The flanged projection 68 upon the dial 15 is formed with a box, 44, on its under side, which is fitted with a backstop, 43, Fig. 13, which engages the ratchetwheel 33, and is kept up thereto by the spiral metallic spring 43.

The operation ofour earlessautomatic word counter and register as described above is as follows: The depression of thelevers 7and 7bythe use of the spacing key or bar 1% draws down the conneetinglink S", which, acting through the crank 23 and the ratchet-lever 31, rotates the ratchet-wheel 33, advancing the pointer 16 one division on the dial 15, the ratchet-wheel at the same time advancing one tooth on the backstop 43, which prevents its back-lash or rebound. The spacingkey or bar 14 may now be struck repeatedly for any required space and the foregoing operation then repeated, as hereinbefore described. W'hen the pointer 16 has completed the circuit of the dial 15, the leadingscrew 34 has described one revolution and carried the half-nut 37, with the pointer 40, to the first division on the scale 38, thus registering the number of words or characters counted on the dial 15. By the continuance of this action the half-nut 37 travels along the leading-screw 3i, registering with the pointer 40 on the scale 38 the successive circuits of the pointer 16 round the dial 15.

The total count at the conclusion ofthe work is shown by the number registered by the divisions on the scale 38 added to the number counted on the dial 15. No mistake can be made in the total count, the intermediate numbers between the scaledivisions being found on the dial 15. At the end of the scale, or at any point upon it at which a piece of work may be completed,the half-nut37 can be lifted off the leading-screw 31 and scale 38 by the knob 71 and placed at zero, and the poi ntcr 16 can also be turned to zero on the dial 15 without reversing the mechanism, as hereinbefore described.

The scale 33 may be of any length suitable to the machine, and the numeral capacity of our counting and registering device may be determined by properly proportioning the diameter of the dial of the ratchetwheel, the pitch of the leading-screw, the length of the scale, and the pitch of the divisions thereon to each other.

Our automatic word counter and register may be adapted for use with anykind of typewriting machine without being attached thereto, as shown in Figs. 22 and 23. i

The counter and actuating mechanism, as hereinbefore described, are mounted upon an independent base or foundation plate, B, which is made of wood or any other suitable material, and is provided with bosses E to receive the feet F of the machine, or with any other means of supporting the same when placed upon it. The weight of the machine would be sufficient to keep it down steady upon the base plate; but it could be clamped or otherwise secured, if desired. Two bearings, O, are fixed upon the base-plate B for the rocking spindle 3 to work in, and a solid block, G, is formed upon one side of the same to support the counter 10, which is fixed upon it in the required position by the screws 25 through the foot 10 thereof.

The construction and operation of the whole of the mechanism is precisely as hereinbefore described, excepting a modification of the means of contact between thelever end 11 and the striking-key 14. of the caligraph, as follows: Instead of the slotted link 8, attached to the under side of the lever end 11, we fi'x a vertical striking-spindle, 14, on the upper side thereof by means of the holes 13. This striking-spindlehasaslotted cross-headfi, in which works the pin 79 of the counter 10, and at its upper end a radial bearing-piece, 12, for the spacingkey lever 14 to work upon.

All the parts are made adjustabie with setscrews or the like, so as to be easily adapted to any machine in use, and any counting and registering device may be employed, motion beingtransmitted thereto in the manner herein set forth.

Having now particularly described and as certained the nature of our said invention and in what manner the same is to be operated and performed, we declare that what we claim is- 1. A counting apparatus for a type-writer, provided with a rocking spindle extending transversely between the side frames of the machine under the horizontal key-levers thereof, with arms or levers extending beneath the spacing-keylevers, but not connected thereto, and with other arms or levers extending beneath the printing or type key levers, but not connected thereto, substantially as described, so that the counter maybe actuated once in the spacing operation of the type-writer after each word written, but such actuation of the said counter more than once after each word may be prevented.

2. In a counting and registering apparatus for a type-writer, the combination,with acounter, of a rocking spindle, 3, extending transversely to the horizontal key-levers l of the type-writer, provided with arms or levers 7. extending beneath the spacing-key levers 14 or 45, and with other arms or levers, 73, extending beneath the said key-levers 1 of varying length to suit the throw of the several levers, substantially as and for the purpose shown and described.

3. In a counting and registering apparatus for a type-writer, the combination, with the dials 15, of the hands or pointers 16 17 18 19, formed with an internal cone in theirbosses,the conical seat 69 on the spindles for the said hands to work upon, and the nut 70 to retain the said hands in frictional contact with the said conical seat, substantially as and for the purpose specified.

4. In a counting and registering apparatus for a type-writer, the combination,with a dialplate, 15, of a leading-screw, 34, a pointer, 16, on the end of said leading-screw to indicate upon the said dial-plate, a graduated registering-scale, 3S, and a halfnut, 37, with a pointer, 40, to indicate upon the said graduated scale, and so arranged that it may be disengaged from the said leading-screw and scale and moved back to zero, substantially as and for I WILLIAM SPENOE.
